I have an almost 11month old and he usually has 2 naps a day. In the morning he wakes up at 6, has a feed and then goes back to sleep – sometimes for 2 hours. He then has another nap either late morning or early afternoon. I think every baby is different though – as long as they are happy and growing and developing well, I wouldn`t worry to much – apart from the fact that you get a well needed break when they sleep!
